How To Register Secret Code

Required Special Tools: 

• MB991958: M.U.T.-III Sub Assembly
  • MB991824: Vehicle Communication Interface (V.C.I.)
  • MB991910: M.U.T.-III Main harness A

Each individual secret code is registered inside the transmitter, and so it is necessary to resister these codes with the EEPROM inside the receiver in the following cases.

• When the transmitter or ETACS-ECU is replaced
• If more transmitters are to be used
• If it appears that a problem is occurring because of faulty registration of a code.

A maximum of four different codes can be stored in the EEPROM memory (four different transmitters can be used). When the code for the first transmitter is registered, the previously registered codes for all transmitters are cleared. Therefore, if you are using four transmitters or are adding more transmitters, the codes for all transmitters must be registered at the same time.
